What Are Blu-rays and How Are They Better than DVDs?

Blu-ray discs are a form of optical storage similar to DVDs. However, instead of using red lasers to burn data onto DVD discs, Blu-rays use a violet-blue laser, hence the name Blu-ray. Since Blu-ray discs use a different laser format to store data, it allows for the data to be placed closer together, thus increasing the storage capacity from 4.7 GB on a single layer DVD to 25 GB on a single layer Blu-ray disc.

Due to the larger storage capabilities, Blu-ray discs are able to store high definition (HD) video and picture content, which standard DVDs cannot. This feature has made Blu-rays more popular in recent years as more people have switched to the newer technology. As HD technologies continue to become more prevalent and used by more people, the expectation is DVDs will eventually stop being used, much like how DVDs displaced VHS tapes.

Blu-ray technologies are backwards compatible with both CDs and DVDs. As a result, Blu-ray players and optical drives are able to support these formats to playback music and movies, as well as access pictures and other data stored on CDs and DVDs. In addition, Blu-ray discs have a hard coating on them, which DVDs do not, that helps prevent against scratching and protects the contents of the disc.
